I wonder if you string together enough words can it be a valid key?
I would hope so, sentences and words are some of the most secure passwords/phrases you can use
Words are the least secure way to generate a password of a given length because you are limiting your character set to 26, and character N gives you information about the character at position N+1
The most secure way to generate a password is to uniformly pick bytes from the entire character set using a suitable form of entropy
Edit: for the dozens of people still feeling the need to reply to me: RSA keys are fixed length, and you don't need to memorize them. Using a dictionary of words to create your own RSA key is intentionally kneecapping the security of the key.
Sounds like a good point, but claiming that “Words are the least secure way to generate a password 84 characters long” would be pointless.
and some people will try to just hold a key down until it reaches the length limit.. which is an even worse way to generate a password of that length
